all need to be used in conjugation with an energy storage system to provide smooth power leveling. Currently, electrochemical energy storage systems are by far the most optimal solutions for powering a broad range of technologies, expanding from compact and light-weighted portable electronic devices to stationary gridscale energy storage applications. [3][4][5][6] These energy storage devices (batteries and supercapacitors) store the available electrical energy in the form of chemical energy and release it whenever needed, by simply reversing the electrochemical reaction. [7][8][9][10][11] Among various available battery chemistries, lithium batteries and supercapacitors are the most promising technologies. [ 7,[9][10][11][12][13][14][15][16][17][18][19][20] Ever since the realization of the fi rst electrochemical energy storage cell by Alessandro Volta (end of 17th century), the working principle and its function has changed very little. [ 21,22 ] Basically, two redox couples (or charge storage electrodes), electrically and physically separated, are bridged by an ion conducting medium to constitute an electrochemical cell. This holds true also for modern Li-ion batteries, although the chemistry involved is much more complex. During operation, the electrons are transferred through an external circuit while ions shuttle through the electrolyte to counterbalance the depleted charge at the electrodes. [ 23 ] So far, much of the effort has been directed towards improvement of the energy and power characteristics by downsizing the active components, re-engineering the current collectors and separators, as well as fi ne-tuning the Batteries have become fundamental building blocks for the mobility of modern society. Continuous development of novel battery chemistries and electrode materials has nourished progress in building better batteries. Simultaneously, novel device form factors and designs with multi-functional components have been proposed, requiring batteries to not only integrate seamlessly to these devices, but to also be a multi-functional component for a multitude of applications. Thus, in the past decade, along with developments in the component materials, the focus has been shifting more and more towards novel fabrication processes, unconventional confi gurations, and additional functionalities. This work attempts to critically review the developments with respect to emerging electrochemical energy storage confi gurations, including, amongst others, paintable, transparent, fl exible, wire or cable shaped, ultra-thin and ultra-thick confi gurations, as well as hybrid energy storage-conversion, or graphene-incorporated batteries and supercapacitors. The performance requirements are elaborated together with the advantages, but also the limitations, with respect to established electrochemical energy storage technologies. Finally, challenges in developing novel materials with tailored properties that would allow such confi gurations, and in designing easier manufacturing techniques that can be widely adopted ar...

“…However, one of the major drawbacks of silicon is the ~300% volumetric change upon charging and discharging, which results in peeling and pulverization of the electrode and eventual capacity loss. Numerous works have been carried out to address these issues, such as using nano-enabled silicon structures, preparing Si/C composites to improve electric conductivity and constructing porous structure or compositing with other active/non-active matrix to buffer the volume change [30,31,32,33]. Considering the structure stability of LTO, it is expected that LTO can also alleviate some of the volumetric expansion of silicon during the cycling process by acting as a buffer.…”

Improving the energy capacity of spinel Li4Ti5O12 (LTO) is very important to utilize it as a high-performance Li-ion battery (LIB) electrode. In this work, LTO/Si composites with different weight ratios were prepared and tested as anodes. The anodic and cathodic peaks from both LTO and silicon were apparent in the composites, indicating that each component was active upon Li+ insertion and extraction. The composites with higher Si contents (LTO:Si = 35:35) exhibited superior specific capacity (1004 mAh·g−1) at lower current densities (0.22 A·g−1) but the capacity deteriorated at higher current densities. On the other hand, the electrodes with moderate Si contents (LTO:Si = 50:20) were able to deliver stable capacity (100 mAh·g−1) with good cycling performance, even at a very high current density of 7 A·g−1. The improvement in specific capacity and rate performance was a direct result of the synergy between LTO and Si; the former can alleviate the stresses from volumetric changes in Si upon cycling, while Si can add to the capacity of the composite. Therefore, it has been demonstrated that the addition of Si and concentration optimization is an easy yet an effective way to produce high performance LTO-based electrodes for lithium-ion batteries.

Trilayered Pd/MnOx/Pd nanomembranes are fabricated as the cathode catalysts for Li‐O2 batteries. The combination of Pd and MnOx facilitates the transport of electrons, lithium ions, and oxygen‐containing intermediates, thus effectively decomposing the discharge product Li2O2 and significantly lowering the charge overpotential and enhancing the power efficiency. This is promising for future environmentally friendly applications.
